When subtracting integers, you add by the opposite sign. Right now, you are subtracting 9 by -4. Change this to adding 9 + (+4). Of course, 9 + 4 = 13.

The answer is 13 or D.

Let f={(1,2),(2,3),(5,6),(7,8) evaluate f(2)and f(5)?​
Flauer [41]

Given:

f=\{(1,2),(2,3),(5,6),(7,8)\}

To find:

The values of f(2) and f(5).

Solution:

If an ordered pair (x,y) is in the function f, then f(x)=y.

In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get

f(2)=3

In the given set of ordered pairs one ordered pair is (5,6). So, by using the above definition, we get

f(5)=6

Therefore, the value of f(2) is 3 and the value of f(5) is 6.

68 miles to 42.5 miles
Thepotemich [5.8K]
1) subtract 42.5 miles from 68 miles to find the gross change in distance:  It is 25.5.  Since this is a decrease, write -25.5 miles.
2) divide -25.5 miles by the original distance, 68 miles:
     -0.375
3) multiply this by 100% to find the percentage decrease:
     -37.5% (answer)
